Best way to tile shower corners to prevent leaks?

will be using 4x10 subway tiles. When it comes to tiling the shower corners I was going to tile the back wall and then butt the side wall tiles. Should I butt the tiles or leave a space (1/16) and use silicone? Or is there a better way?

First off, you dont "prevent leaks" with tile, or by the way you lay tile. To prevent leaks you lay tile on a waterpoof surface... Ditra, Kerdi, Wedi, or Redgard... to name a few.

As for how to lay tile in a corner, leaving a 1/16 to 1/8" gap is appropriate. This gap should not be grouted, instead you typically use a color matched grout caulk which comes in sanded or unsanded textures to match your grout.

Changes in plane - corners - get caulk instead of grout.

As stated, tile and grout/caulk are not waterproof.

I'll be the third person to reiterate that tile is not the waterproofing for a shower. There must be a waterproof membrane installed BEFORE tiling.

Thanks for the advice guys. I have waterproofed with kerdi board. can you tell me if It's best to use a silicone caulk to help minimized mold or a color matched grout caulk would be fine?

Most color matched caulk is intended for tile/shower use and is mildew resistant.
